Hello world!

YAB is on the web. I had hard time picking right technology, what I wanted is blog as simple as it can get. At the end of the day Jekyll won over chirp and octopress.

Installation of Jessie left me with two problems and right after that I want to restore my default setup. To the point!

Two problems with my Dell

  • WiFi not working.

    Let’s check what we have:

 
    lspci

    02:00.0 Network controller: Intel Corporation Wireless 7260 (rev 73)

To fix it you need drivers that are in non-free packages.

 
    sudo sed -i.bak 's/main contrib/main contrib non-free/' /etc/apt/sources.list'
    sudo aptitude update && sudo aptitude install firmware-iwlwifi

  • CPU freaks out after waking up from sleep.

    Let’s go!

 
    sudo aptitude install cpufreqd cpufrequtils

Automate all the things!

I use puppet but I don’t want to start flame war.

Some of the stuff is puppet code but of course I need to restore some files too like autofs, sudoers, hosts, etc.. I have divided my setup to sections, you can save code to file such as ‘awesome.pp’ and then execute it with puppet apply awesome.pp

    unless => "/bin/grep 'source /opt/bash-git-prompt/gitprompt.sh' /etc/bash.bashrc",
  }

These are all snippets of code, but man they come real handy when you want your default configuration on laptop :)

Treat your configuration as code, make everything volatile and stop worrying about tomorrow!

Bye bye, see you real soon!
